Abstract

L'invention a trait à une composition extrudable constituée d'un moins deux polymères thermoplastiques dans une structure à deux constituants. L'un des polymères thermoplastiques est présent en tant que phase dispersante dominante et l'autre polymère, sinon plusieurs autres polymères, en phase(s) dispersée(s), sous des quantités inférieures à environ 15 % en poids. Le point de fusion du polymère de la phase dispersée, ou des phases dispersées, est inférieur à 30 °C, au-dessous du point de fusion du polymère de la phase dispersante. Le polymère de la phase dominante est, par exemple, du polypropylène tandis que celui de la phase dispersée peut être, notamment, un polyamide. On peut utiliser cette composition extrudable à la production de fibres d'un diamètre compris, d'ordinaire, entre 5 et 50 microns environ. Ces fibres sont susceptibles de fournir des étoffes non-tissées.
